Title: Method of anisotropically etching barium strontium titanate
Inventor: MONTE EE DAGURASU
IPC: H01L21/02
Filed: 1993-04-19
Abstract: PURPOSE: To provide an anisotropic etching method for barium strontium titanate.  
     CONSTITUTION: A barium strontium titanate substrate 34 is immersed into a liquid atmosphere (for example, hydroacid chloride 30 of 12 mol in concn.) and is illuminated with the electromagnetic radiation (for example, converged visible/UV electromagnetic radiation 24) emitted by a radiation source (for example, a mercury xenon arc lamp 20 of 200 Watt). A window 26 which is intrinsically transparent to the converged electromagnetic radiation 24 permits the arrival of the radiated energy at the titanate substrate 34. An etching mask 32 may be arranged between the radiation source 20 and the substrate 34. The titanate substrate 34 and the liquid atmosphere 30 are kept at a nominal temp. (for example, 25°C). The titanate is hardly etched by the liquid atmosphere without illumination. The etching rate increases intrinsically when the barium strontium titanate is illuminated.

Title: Radio transmission circuit
Inventor: NAKAMURA SHIZUHITO
IPC: H04B1/04
Filed: 1994-04-28
Abstract: PURPOSE:To make the size of the circuit small by controlling attenuation of a variable attenuator with a control signal so as to reduce number of components. CONSTITUTION:A detector 7' gives a signal S11 used to decrease a level of a signal S6 when the level of the transmission signal S6 is higher than a specified level and the level of the signal S6 when the level is smaller to an AGC circuit 3 to keep the signal S6 to have a specified level. An IF signal detector 22 detects an IF amplifier signal S3 being an output of the circuit 3 and provides an output of a control signal S12 of a prescribed level when the signal S3 is present and a signal S12 of 0V when absent to a variable attenuator VATT21. When the detector 22 detects the signal S3, the signal S12 used to decrease gradually the attenuation of the VATT21 is provided as an output and the signal S3 passes gradually and a mixer 4 provides an output of a high frequency signal S5 gradually getting higher and it is amplified by an RF amplifier 6 to increase the level of th signal S6. A control signal S11 being an output of a detector 7' is used to decrease the gain of the circuit 3 based on the level of the signal S6. The operation above is repeated depending on a lapse of time and the signal S6 is finally made stable to the specified level.

Title: Device for balancing inertia force of pilger mill
Inventor: TAKAHASHI MUNEHARU
IPC: B21B21/00
Filed: 1987-04-16
Abstract: PURPOSE:To miniaturize the facility by connecting a pilger mill stand to a 1st fluid cylinder, interlocking a balance weight which has an equal weight to that of the stand and moves in the opposite direction, connecting the weight to a 2nd fluid cylinder, and both the cylinders are installed on one base. CONSTITUTION:A Pilger mill stand 8 reciprocates by actuation of a main motor 1 and a reciprocative inertia force balances with a compressive force in a 1st air cylinder 15. By the reciprocation of the stand 8, a balance weight 12 having an equal weight to that of the stand 8 interlocks with the stand 8 through a rack 13 and a pinion 11, so that the stand 8 and the weight 12 reciprocate in opposite directions to each other at the same speed and the same position change on a common base 14. The reciprocative inertia force of the weight 12 balances with a compressive force in a 2nd air cylinder 21. Respective reaction forces of those compressive forces are internally canceled in the common base 14. An optimum air volume is calculated by an air volume arithmetic unit 26 in proportion to a rotating speed of a crankshaft 2 and the compressive force in the air cylinders 15, 21 is adjusted by opening or closing an air tank 23. Thus, the facility is made compact and high speed.

Title: Shell-and-tube adsorption apparatus
Inventor: OCHIAI KIYOSHI
IPC: B01D53/04
Filed: 1985-04-27
Abstract: PURPOSE:To contrive prolongation of the breakthrough time and the increase of the purity by connecting the other adsorption pipe in series which has a crosssection area smaller than the whole crosssection areas of a main body part with an outlet side of the main body part wherein plural adsorption pipes are parallel connected thereto. CONSTITUTION:Gas is introduced to the inside of a main body part 1 wherein plural adsorption pipes 2 are parallel connected thereto and N2, O2 being the impurities are adsorbed and removed. When feeding the gas continuously, the main body part 1 is broken through but because an adsorption pipe 3 of an aid part connecting to an outlet side thereof in series is present, it is not broken through until the adsorption pipe 3 is broken through. Since the adsorption pipe 3 having a crosssection area smaller than the whole crosssection areas of the main body part is used, the gas flow velocity of the aid part is increased and the amount of the unsaturated adsorbent in a breakthrough time of the aux. part can be retained to a small quantity.

IPC: G06F11/00
Filed: 1984-05-09
Abstract: PURPOSE:To set many kinds of timers simultaneously and to make set timers ineffective at a high speed by providing a RAM (TAM) where the addresses of idle areas of a RAM (TCM) holding timer control words are held. CONSTITUTION:A program executes the output instruction of timer set to output a timer control word TCW, thereby setting a timer. A timer control part uses the value of an address pointer register PTR1 as the address to read out one idle area address of a TCM10 stored in a TAM11 and sets this address to a pointer PTR2 and subtracts one from the value of the PTR1 thereafter. This idle area address is used as the address to store the TCW in the TCM10, thereby terminating timer set. The program execute the output instruction of timer cancel to output the address of the TCM10 where the TCW of the timer to be made ineffective is stored, thereby making the timer, which is set once, ineffective.

Title: Mouth-sealing method for container for latent-heat heat-accumulating material
Inventor: YAMASHITA KAZUO
IPC: F28D20/02
Filed: 1984-05-09
Abstract: PURPOSE:To obtain a heat-accumulating container having high bond strength and high reliability, by a method wherein a pair of films are seamed to each other while leaving a pourig port, a latent-heat heat-accumulating material is poured into a bag form body thus obtained, the port is sealed, and after washing the part near the port, sealing is further conducted on the outside of the sealed port. CONSTITUTION:A pair of laminate films 2 are welded to each other along the periphery thereof while leaving an inserting port 3 for a heat-accumulating material to obtain a bag form body having a bonded part 4, and a large amount of sodium acetate trihydrate as a heat-accumulating material is poured into the bag form body, followed by welding to provide a bonded part 5. In this case, welding is conducted with the salt clamped between the laminate films, so that the bond strength is low. After cooling, the bag form body is washed with water at room temperature to remove the salt adhered to the part near the bonded part 5. Since this removal is conducted at room temperature, the heat-accumulating container shows high strength and is not broken at the time of washing. After washing, the container is dried, and a bonded part 6 is provided by thermal welding on the outside of the bonded part 5. In this case, since bonding of the part 6 is conducted in the absence of the salt clamped between the laminate films, the bond strength is high, and the container is not broken in use.
